To alien/10m it may romw'n: i

Be it known that 1, CHARLES lvlc-Knnvnn, a citizen of the United States,residing at Jersey City, county of Hudson, and State of New Jersey, haveinvented an Improvement in Vehicle-Lamps, oi which the following is aspecification. 4

My present invention relates to a lamp and particularly to a lampadapted for use in a motor vehicle. So far as I am aware the lampscommonly employed on motor vehiclesincluding automobiles, trolley carsand the like, are made with a reflector adapted to receive a socket and,an electric lam p bulb. in this form of lamp irrespecthe ot the positionthe bulb may assume, the filaments of the bulb are visible and the lightreflected by the reflector oftentimes causes such a glare as to make itimpossible well as around a portion of the socket, and a cap memberpreferably comprising a rim adapted to be secured to the edge of the cupand a disk provided with an aperture to receive the point of the lampbulb so that the cup is supported and maintained in-position upon thelamp socket and by the said cap, the disk of which makes it impossibleto view directly the filament of the lamp bulb while the cup member isso constructed as to diffuse and direct the light to the amount and inthe direction required by the law in many places.

In the drawing Figure 1 is a central cross section f a vehicle lamp madein accordance with my invention. Fig. 2 is a plan view of the cup andcap in position relatively to the lamp bulbL Referring to the drawing,10 indicates a reflector which may be suitably secured in any form ofcasing commonly emplpyed in lamps for motor vehicles. At the 'base ofthe reflector the same is provided With a lamp' socket 11 which may befixed in position as shown in Fig. 1 or made adjustable to positionwithin predetermined limits to regulate the focus of the light. As iscus tomary an electrical lamp bulb 12 is employed. This lamp bulb isprovided with a base 13 having oppositely disposed pins 1% adapted toenter the slots 15 in the lamp socket .11 to secure the lamp bulb inplace and make the necessary electrical connections for lighting thelamp.

Together with these features which heretofore h i/e been commonlyemployed in vehicle lamps, I employ a cup member 16 made of suitableglass or other sufliciently transparent material. The base of the cupmember 16 is provided with an opening 17,

adapted to receive the end of the larripv socket 11. The periphery ofthe cup member 16 adjacent the edge thereof is preferably ribbedindicated at 18, while that portion 19 of the cup adjacent the base isplain; The object of this disclosed in my co,-

pending application, Serial No. 107,078,

filed July 1, 1916,;is to d'll'use the rays of light from the lam p, andto direct them immediately in front of the lampvvithin a predeterminedscope depending upon the area of the plain surface at the base of thecup member, it being apparent that the rays of light'passing through theribbed por tion of the/cup member will be generally diii'used by thereflector, while the rays of light passing through the base of the cupmember will he reflected through the same again immediately in limit ofthe-lamp.

In my present invention I also employ a although it inay be constructedof other suitable material. This cap member con); prises a rim 21,adapted to lit and be connected to the edge of the cup member as wellasa disk 22, provided with a central opening 21-). to receive the pointbulb. The disk 22 is connected to the rim 21 by means of suitablyspacedarms 25 'or .adjacent the edge thereof in order to secure the capin position, it being apparent as hereinhe-fore stated that the cupmember is supported and maintalned in'position by cap member 20,preferably made of metal,

24: of the lamp 7 and having an openin the lamp socket, the cap and thebulb. It will also be understood that when the socket is made adjustableto position it may be moved toward the reflector until the cup contactswith the reflector and this also assists in maintaining the cup inplace.

.I claim as my invention:

1. In a vehicle lam and in combination with a lamp bulb an' a sockettherefor, a transparent cup fitting over said lamp bulb, in the basethereof to receive the said soc at, and a device secured t0 the edge ofthe cup to prevent the direct vision of the filament in the lamp bulb,and to co-act With the lamp socket and bulb in maintaining the cup inposition.

2. In a vehicle lamp and in combination witha lamp bulb and a sockettherefor, a glass cup fitting over said lamp bulb and having an openingin the base thereof to receive a portion of the said lamp socket, andacap securedigtoi the edge of the said cup to prevent theidirect visionof the filament in the lamp blilbt'ieand to co-act with the lamp socketandybulb in maintaining the cup in position 3. In a vehicle lamp and incombination, with a lamp bulb and a socket therefor, a glass cup fittingover said lamp bulb and having an opening in the base thereof to receivea portion of the said lainp socket, a

rim secured to the said glass cup, and a disk connected to'the said rimand adapted to prevent the direct vision of the lamp bulb filament, andalso to co-act with the said lamp socket and bulb to maintain the glasscup in position.

4;. In a vehicle lamp and in combi 1ation with areflector, an electriclamp bulb and a socket therefor, a glass cup fitting over said electriclamp bulb, and having an opening in the base thereof adapted to receivea portion of the lamp socket, a disk having an aperture therein toreceive the point of the electric lamp bulb, a rim adapted to be securedto the edge of the glass cup, and means connecting the said disk andrim.

5. In a vehicle lamp and in combination with a reflector, an electriclamp bulb and a socket therefor, a glass cup fitting over said electi iclamp bulb, and having an opening in the base thereof to receive aportion of the said lamp socket, a disk having a central aperture toreceivethe point of the electric lamp bulb, a rim, means connecting thedisk and rim, and lugs on the inner side of the said rim adapted toengage the edge of the glass cup to secure the said rim and disk inposition thereon.

Signed by me this 21st day of September, 1916.
